Me and my boyfriend had been trying to get pregnant last 8 months. I Normally have a period at the end of every month around the 27th. Well in December I didn't have a period. It came on January 4th. Me and my boyfriend split up for a lil while and regretfully and embarrassingly I slept with someone else and had unprotected sex on January 14th. I missed my period in February and went to the dr on February 23rd and they said 7 weeks. Went back and had an ultrasound on March 5 and it said I was 9 weeks pregnant. Could you please tell me when I got pregnant so I can quit feeling guilty!
